JAMES S. FOX, OF WOODSTOCK, VERMONT.

SPECIFICATION forming part of Letters Patent No. 269,845, dated January 2, 183.

Application tiled January. 14, 1882. (No model.)

To all whom fit may Concern Beit known that I, JAMES S. FX,Aacitizen of Ontario, Canada, residing at Woodstock,

in the county of Windsor and State ot Vermont, have invented an Improved Clamping or Fastening Device for Securing Barbed Wire to Iron Fence-Posts, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which-' Figure 1 is a side elevation of an iron fencepost having my improved clamping or fastening device for securing the wire applied thereto. Fig. 2 is a longitudinal vertical section through the center of the same. Fig. 3 is a perspective view ofthe clamping or fastening device detached. Fig. 4 is a transverse section on the line :c a' oi' Fig. 1.

My present invention has for its object to provide a simple, durable,and efcient clamping or fastening device for securing barbed wire to iron fence-posts, which device can be readily adjusted upon the post in any desired position, thus enabling the barbed wires to be easily arranged and secured at any desired distance apart; and my invention consists in the combination of an angular fence-post with a sliding collar provided with a sharp-edged projection, between which and the post the wire is clamped, anda notched or grooved wedge which passes through the collar, and which has a head to catch over the collar and a guide to catch against the post below the collar,as will be more fullydescribed hereinafter.

In the said drawings7 A represents a tubular iron fence-post, of rectangular form in cross-section, which is provided at its lower end with a sharp-pointed shoe to facilitate the operation of driving it into the ground.

Upon the post A are loosely fitted a series of metal collars,B, one for each line of barbed wire O intended to be secured thereto. The contour of thev interior of each collar B vcorresponds' to that ofthe post A, upon which it is adapted to slide freely up and down,to admit of its being adjusted in any desired position in accordance with the required distance apart of the lines of barbed wires to besecurcd to the post.

On the upper side of the collar B, at one end, is a curved projection, b, which is placed opposite to and embraces the corner or angle 1() of the post A, the projection inclining slightly inward from the bottom toward the the collar is asqu'are recess, c, into which is itted a wedge, D,`which, when loosened or drawn up,allows the collar to be freely moved to its desired position, and also allows the projection b to be drawn back sufficiently to at'- ford ample space between it and the post to admit the barbed wire O', which then rests against the corner or angle 10 of the post and the two sharp holding-edges 12 l2 of the projection l). The wedge D is nowl driven down between the collar and the post,which notonly causes the collar to be firmly secured in place, but draws forward the projection b, causing its holding-edges 12 12 to bend the wire O over the corner or edge 10 of the post, as seen in Fig. 4, this bending of the wire at au angle over two sharp edges, 12 12, and around a third bearing point or edge, 10, arranged be* tween the two, causing it to be securely clamped or fastened in place in such manner that it will successfully resist any strain in the direction ot' its length to which it would ever be liable to be subjected, thus preventing the annoyance frequently caused by the wire slipping and becoming slack during the operation of stretching it upon the posts.

The wedge D is lprovided at its lower end with a curved enlargement, d, which embraces the corner of the post A, and serves not only as a guide to keep the lower edge of the wedge in place as it is moved up or down,butto prethe aperture or. recess c of the collar when the latter is in place upon the post, thus preventing the accidental loss of the wedge, which is also provided at its upper end with another grooved guide, c, which lits over the corner or ing to steady the wedge in its movements and avoid any possibility of its being laterally displaced or moved out of its proper operating' position.

The above-described clamping` or fastening device may be employed in connection with metallic fence-posts of any description, either solid` or hollow, which will admit of the wire being bent'so as to take a bearing upon the edge of the pos-t A, these two guides d e servtop, as seen in Fig. 2. At the opposite end of ventthe wedge D from being drawn up through IOO post and the two edges 12 12 of the projection b ofthe collar, the contour ot' the interior ofthe collar beingmade in every case to correspond to the shape of the post in cross-section, to which it is applied.

Any desired number ot' these clamping dcviees may be Yplaced upon a post, whereby a series of wires may be readily secured at any desired distance apart, and the necessity of boring.Y holes in the posts, as heretofore, for the reception ofthe clamps is thus entirely avoided,togethcr with the anno) anco and inconvenience so frequentlycaused by tinding the holes in the posts in the wrong positions to admit ot' the wires being placed at the required distance apart.

What l claim as my invention, and desire to secure by Letters Patent, is-

1. The combination ot' the post A, the collar B, provided with the proiection b, having the sharp edges 12, with the wedge D, notched or g'rooved on its inner side, and having the head e, to catch over the top ofthe collar, and the guide d, to catch against the side of the post, substantially as shown.

2. In a clamp for securing barbed wire to fence-posts, the combination, with the collar and fence-post A, ot' the wedge D, provided with guides d e, adapted to tit the edge or corner ot' the post and keep the wedge in position, substantially as set forth.

fitness my hand this 2d day of January, A. D. 12582.
